It was very useful to get this card because you use it to access to lot of mountain lifts. Our hotel got for us as part of our accommodation package. It is suggested to get one if you are planning to visit around Oetz region.

Where we stayed: Alpengasthof Grüner
Austrian restaurant in Solden:
s’Pfandl
wine & dine – a la carte restaurant (they only open in winter season, so we didn’t actually go there for dinner during our holiday. However they do have a good review online. And when we called to book the lady answering the phone was very polite and nice to explain the situation. Seems a good place.)
